What do you mean by multithread program in java?
A Program in Java that spawns multiple threads is called a multithreaded program in Java.
What components of program state are shared across threads in a multithreaded process?
Obviously Heap Memory
Write a program that generates the Fibonacci series up to 200?
class Program { static void Main(string[] args) { int n1, n2, n3,i; n1 = 0; n2 = 1; for (i = 1; i <= 20; i++) { n3 = n1 + n2; if (n3 <= 200) { Console.WriteLine(n3); n1 = n2; n2 = n3; } } Console.ReadKey(); } }
Can you explain the program of Fibonacci series in c?
You mean you have written a program, but you don't understand it? Well, how could I explain it without seeing it?
Write a program to print the Fibonacci series in php upto input value using recursive function?
The Fibonacci sequence uses recursion to derive answers. It is defined as: F0 = 0 F1 = 1 Fn = F(n - 1) + F(n -2) To have this sequence printed by a php script use the following: function fibonacci($n) { if($n 1) return 1; //F1 else return fibonacci($n - 1) + fibonacci($n - 2); //Fn } This recursive function will print out the Fibonacci number for the integer n. To make it print out all the numbers in a particular set add this to your script. for($i = 0; $i < 15; $i++) { echo fibonacci($i) . "<br />"; } So your final result would look like. <?php function fibonacci($n) { if($n 1) return 1; else return fibonacci($n - 1) + fibonacci($n - 2); } for($i = 0; $i < 15; $i++) { echo fibonacci($i) . "<br />"; } ?>
What mean by multithreaded program?
A multithreaded program is one that has multiple threads in execution. They may execute parallel to one another or totally without relation to one another. In Java you can create multithreaded programs using Java threads.

Program that generates and displays the Fibonacci?
/*WAP to display Fibonacci series*/ #include<stdio.h> #include<conio.h> void main() { int i,a=0,b=1,c; scanf("%d",&n); printf("%d\n%d",a,b); for(i=0;i<n;i++) { c=a+b; a=b; b=c; printf("\n%d",c); } getch(); }

Write a c program Fibonacci series using for loop in java?
Exactly what do you mean by 'C program in Java'
Write a program using while loop that generates Fabonaci series up to 200?
//to generate Fibonacci series upto a range of 200....(in C).... #include<stdio.h> main() { int a,b,c,i; a=0; b=1; printf("\n FIBONACCI SERIES .....\t"); i=1; while(i<=(200-2)) { c=a+b; printf("\t%d",c); a=b; b=c; i++; } }
Can you explain the program of Fibonacci series in c?
You mean you have written a program, but you don't understand it? Well, how could I explain it without seeing it?
What is the code of a c program that will read in a positive integer value and determine If the integer is a prime number and If the integer is a Fibonacci number?
see the program
Program to generate Fibonacci series using storage class in c plus plus?
i dn't know. haha
Why java called as multithreaded programming?
Java is called multithreaded because it allows the programmer to define multiple threads of execution manually. The main program would continue to execute as one thread and we can speed up the processing by declaring individual threads. Threads in Java can be created in two ways: 1. By extending the Thread class & 2. By implementing the Runnable interface
In a multithreaded environment a is defined as the unit of resource allocation and a unit of protection?
In a multithreaded environment, a mutex (mutual exclusion) is used as the unit of resource allocation and a unit of protection. It ensures that only one thread can access a shared resource at any given time, preventing race conditions and data corruption. This synchronization mechanism helps maintain data integrity and consistency in a concurrent program.
